The antioxidant capacity of dried Agaricus bisporus mushrooms (DAB) in beef has previously been assessed. However, interactions between lipid oxidation products, mushroom polyphenols, and bovine proteins present in beef to explain the mushroom's antioxidative effect, has not been determined. Oven-dried or lyophilized DAB with and without 15 g NaCl/kg beef (1.5%) or 20 g NaCl/kg beef (2%) were added to sarcoplasmic protein homogenates from top round beef. Malondialdehyde and volatile aldehyde binding to sarcoplasmic protein (SP) were monitored. Oven dried had 64% higher total phenolic compared to lyophilized DAB, leading to ∼50% lower malondialdehyde content in beef with oven …

We recently reported that epicatechin, a bioactive compound that occurs naturally in various common foods, promoted general health and survival of obese diabetic mice. It remains to be determined whether epicatechin extends health span and delays the process of aging. In the present study, epicatechin or its analogue epigallocatechin gallate (EGCG) (0.25% w/v in drinking water) was administered to 20-mo-old male C57BL mice fed a standard chow. The goal was to determine the antiaging effect. The results showed that supplementation with epicatechin for 37 wk strikingly increased the survival rate from 39 to 69%, whereas EGCG had no significant effect. …

Anti-Inflammatory Effect Of Berry Essences, Inah Gu
Graduate Theses and Dissertations
Inflammation is one of defense reactions of our body tissues against harmful stimuli such as infection and tissue injury. However, it has been reported that chronic inflammation can lead to chronic inflammatory diseases including diabetes, cardiovascular diseases and cancer. This transition from acute to chronic inflammation state is usually induced by pro-inflammatory mediators and cytokines including nitric oxide (NO), prostaglandin E2 (PGE2), interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α), which accelerate the development of other chronic diseases. Accordingly, targeting these pro-inflammatory factors is one of the important roles for anti-inflammatory agents. For last two decades, researches about anti-inflammatory …

The utility of characterizing the effects of strain variation and individual/subgroup susceptibility on dose-response outcomes has motivated the search for new approaches beyond the popular use of the exponential dose-response model for listeriosis. While descriptive models can account for such variation, they have limited power to extrapolate beyond the details of particular outbreaks. By contrast, this study exhibits dose-response relationships from a mechanistic basis, quantifying key biological factors involved in pathogen-host dynamics. An …

Obesity is an increasing epidemic which during 2015-2016 afflicted 39.8% of adults and 18.5% of youth in the United States. Not only can obesity affect quality of life, but it can lead to life-threatening diseases such as type 2 diabetes, heart disease, stroke, and some cancers. Animal and human research have demonstrated a pattern of gut microbiota perturbation in overweight and obesity, characterized by a reduction of beneficial bacterial species and increase in harmful species. Diet has been established as a contributing factor in gut ecology, and foods including fiber, resistant starch, and polyphenols have been found to both enhance …

Effects Of Serving Temperature On Sensory Perception And Acceptance Of Brewed Coffee, Matthew James Chapko
Graduate Theses and Dissertations
Coffee continues to be one of the most widely consumed beverages worldwide. How an individual perceives a cup of coffee is impacted by a plethora of factors including origin, growing climate, roasting level, and consumption habits. This thesis utilized both trained descriptive panelists and untrained consumer panelists to analyze how serving/consumption temperature modulates sensory perception of brewed coffee in regards to appearance, aroma, flavor, taste, and mouthfeel. Three varieties of coffee (Colombia, Ethiopia, and Kenya) were brewed and served to panelists at four temperatures: 70, 55, 40, and 25 °C. In one study (Study 1, Chapter 3), results from descriptive …
Influences Of Intrinsic And Extrinsic Hand-Feel Touch Cues On Sensory Perception And Emotional Responses Toward Beverage Products, Ragita Cantika Pramudya
Influences Of Intrinsic And Extrinsic Hand-Feel Touch Cues On Sensory Perception And Emotional Responses Toward Beverage Products, Ragita Cantika Pramudya
Graduate Theses and Dissertations
Consumer perception of and preference toward products are influenced by intrinsic product-specific (e.g., product temperature) and extrinsic non-product-specific (e.g., packaging or container) characteristics. Besides communicating information between products and consumers to create expectations toward the content at the point of sale, packaging also influences sensory perception of the content during consumption. Previous cross-modal studies on packaging effects on the content had largely overlooked hand-feel touch cues. Touch closely relates to consumers’ emotional responses to and their quality evaluation of products. One way to manipulate hand-feel touch cues in a beverage consumption setting is to vary materials of cup sleeve, which …

The biosynthetic pathway for amanitins and related cyclic peptides in deadly Amanita (Amanitace ae) mushrooms represents the first known ribosomal cyclic peptide pathway in the Fungi. Amanitins are found outside of the genus in distantly related agarics Galerina (Strophariaceae) and Lepiota (Agaricaceae). A long-standing question in the field persists: why is this pathway present in these phylogenetically disjunct agarics? Two deadly mushrooms, A. pallidorosea and A. subjunquillea, were deep sequenced, and sequences of biosynthetic genes encoding MSDINs (cyclic peptide presursor) and prolyl oligopeptidases (POPA and POPB) were obtained. The two Amanita species yielded 20 and 18 MSDINs, respectively. In addition, …
